Abstract: A multi-radio mobile device comprises a plurality of different radios. When a location update occurs, the multi-radio mobile device, at a specific location, acquires location-based radio information from a remote location server. The multi-radio mobile device selects a radio for use in the specific location based on the acquired location-based radio information comprising available radios in the specific location and radio weights. The radio is selected from the available radios based on the radio weights in the specific location. Transmissions of a desired service are received in the specific location utilizing the selected radio. Location-based radio measurements reports to the remote location server are generated utilizing signal strength measurements for the received signals. Radio quality information of the available radios is calculated by the location server utilizing location-based radio measurement reports from associated users. The radio weights of the available radios are determined based on the calculated radio quality information.

Abstract: A broadband gateway, which enables communication with a plurality of devices, handles at least one physical layer connection to at least one corresponding network access service provider. Security boundaries such as conditional access (CA) and/or digital right management (DRM) boundaries associated with the broadband gateway are identified based on security profiles associated with the plurality of devices and/or a service from networks. The identified security boundaries are utilized to determine or negotiate CA information for content access for the service. The received content may be distributed according to the determined CA information and the security profiles of the corresponding devices. The broadband gateway may be automatically and dynamically configured based on the identified security boundaries to secure content distribution to the devices. Content distribution security schemes, for example, super encryption, simul-crypt, IPSec and/or watermarking, may be selected by matching the CA information with corresponding device security profiles.

Abstract: A mobile device may be operable to determine, based on a known location of the mobile device, a location for a RF communication device that communicates with the mobile device, whenever the mobile device is within proximate range of the RF communication device. The determined location for the RF communication device may be stored in a location database in a location server and/or a memory in the RF communication device. The stored location of the RF communication device may then be used to determine a location for other mobile devices that may communicate with the RF communication device and are within proximate range of the RF communication device. The RF communication device may comprise a radio-frequency identification (RFID) device and/or a near field communication (NFC) device. The determined location for the RF communication device may comprise the known location of the mobile device.

Abstract: A broadband gateway may be used to authorize transactions associated with one or more accounts, which may be associated with a user of the broadband gateway. The transaction may be handled by the broadband gateway. The authorizations may be performed based on information associated with the accounts, whose storage may be controlled by the broadband gateway. The broadband gateway may block and/or terminate transactions failing authentication and/or validation, which may be performed based on the stored information. The transactions may be initiated within a network serviced by the broadband gateway. The transactions may also be initiated outside the serviced network. The stored information may comprise a user profile, which may comprise a plurality of settings for controlling and/or managing authorization performed by the broadband gateway. The user profiles may be configurable by users, wherein configuration may comprise initializing and/or modifying one or more of the transaction related settings.

Abstract: A transmitting communication device may iteratively adjust its transmit power, and may estimate, based on iterative transmit power adjustment, relative location of a receiving communication device. The transmit power may be initialized to a maximum value, and the transmit power may be iteratively reduced until connectivity with the receiving communication device is lost. The loss of connectivity may be determined based on reception of responses to ping messages transmitted by the transmitting communication device. The transmitting communication device may authenticate the receiving communication device and/or a user of the receiving communication device. The authentication may comprises utilizing transmit power adjustment and/or relative location estimation therefrom to ensure that a separation between the devices does not exceed a maximum value. The transmitting communication device may generate location info associated with the receiving communication device based on the relative location estimation, and may communicate the location info to a location server.
